Abstract
The utility model relates to a rail bottom hook head bolt, consisting of a hook head part and a bolt part. The shape of the hook head corresponds to the shape of the rail bottom; when the hook head bolt is arranged, the hook head hooks the bottom at one side of the rail; the bolt tightly clings to the rail bottom and extends to the other side of the rail. The shape of the hook head can be made into shapes corresponding to various shapes of the rail shape bottom according to requirements; the cross section of the hook head can be processed into various shapes such as round, waist round, oval, square or rectangle, etc. according to requirements. The utility model is of simple and reasonable structure, convenient assembly, low production cost, firm and reliable connection of the equipment and devices arranged on the rail.
Description
Technical field
The utility model relates to a kind of fastening piece of railway track; Relate in particular to a kind of rail foot j-bolt that relevant devices or device is fixed on the rail side.
Background technique
Various device and device are installed on railway track at present, and general the employing holed on the rail road web of the rail, uses bolton; Perhaps the clamp that adapts with a pair of and flange of rail shape at the flange of rail at the flange of rail, is installed various device and device with bolt clip then on clamp; Have plenty of at equipment and directly design a bayonet socket suitable mutually, load onto the clamp that adapts with flange of rail shape, clamp with bolt then at the another side of rail with flange of rail shape with installing.The connection set that said structure is assembled exists complex structure, the high deficiency of processing cost.
Summary of the invention
The utility model mainly is to solve the existing in prior technology deficiency, thus develop a kind of simple in structure, processing cost is low, service-strong railway track bottom j-bolt.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of rail foot j-bolt, be grouped into by gib head part and bolt part, it is characterized in that: have bolt, clamp is arranged on the bolt, it is characterized in that: an end of bolt has gib head, when installment state, gib head hooks the bottom of rail one side, bolt is close to the opposite side that the flange of rail reaches rail, by fastening nut, clamp is fixed on rail foot.
The technical solution of the utility model can also be further perfect,
The shape of gib head and the shape of rail foot adapt; The width that the length of j-bolt slightly is longer than the rail flange of rail adds the clamp sum.The gib head shape can be made the shape that adapts with 43kg/m, 50kg/m, 60kg/m, 70kg/m rail and other various rail type bottom shapes as required, and gib head is combined firmly with rail.The diameter of j-bolt can be made the various different sizes that adapt with various rail types.
The cross section of the gib head of described j-bolt can be processed into multiple shapes such as circle, oval shape, ellipse, square or rectangle as required.
Therefore, the beneficial effects of the utility model are to have simple and reasonable for structurely, easy to assembly, and low cost of manufacture also makes the equipment and the device that are installed on the rail be connected firmly, reliably.
Description of drawings
Accompanying drawing 1 is a kind of j-bolt structural representation of the present utility model;
Accompanying drawing 2 is installations diagram of a kind of vehicle speed measuring device;
Accompanying drawing 3 is the installations diagram on a kind of railway common equipment-deceleration top.
Embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment: j-bolt as shown in Figure 1, bolt 1 is arranged, nut 12, gib head 11, the shape of gib head and the shape of the flange of rail adapt, can make as required and 43kg/m, 50kg/m, 60kg/m, the shape that 70kg/m rail and other various rail type bottom shapes adapt, the length of bolt 1 also will adapt to the rail type and change, the diameter of j-bolt can be according to the different different sizes that adapt with various rail types of making of rail type, the cross section of gib head 11 is circle or ellipse or oval shape or multiple shape such as square or rectangle, is generally circle or rectangular cross section.Its gib head 11 of circular cross-section and the flange of rail contact with line or point, and square or its gib head 11 of rectangular cross-section contacts with face with the flange of rail, and stability is better than the former.Be a kind of installation diagram of vehicle speed measuring device as shown in Figure 2, j-bolt is by rail 2 bottoms, gib head 11 matches with a end at the bottom of the rail, clamp 3 matches with the other end at the bottom of the rail, tightening nuts 12,, speed measurement device 4 is installed on the last plane of clamp 3 as mounting base with the last plane of clamp 3.Fig. 3 is the installation diagram on railway equipment commonly used-deceleration top 5, gib head 11 matches with a end at the bottom of the rail, j-bolt is by rail 2 bottoms, through the rail another side, the housing that pushes up that slows down is provided with the clamp 3 that matches with the flange of rail, by fastening nut 12, make the bayonet socket on top 5 housings that slow down just be held in rail 2 bottoms, the top 5 of will slowing down tightly is fixed on the rail.The slow down installation on top of past is that install web of the rail punching back, or with one side housing with bayonet, another side is installed with the mode of clamp clamping.
